- Аннотация: Two series of modified with stearic and oleine acids alumina samples are prepared. Content of the modifiers on the alumina surface is from 0.1 to 4 group/nm2. Dependence of adsorption of nitrogen, water, benzene vapors and acid dye (in aqueous solution) on the modifiers content is studied. Stearate in the sample with its maximum content (2.7 group/nm2 ) present dense monolayer difficult accessible for molecules of the investigated substances. The most active adsorbent of organic ionic substances in aqueous solutions is alumina with stearate content about half of monolayer. The alumina with the maximum oleate content (about 4 group/nm ) absorbed the greatest benzene volume equivalent to three specific pore volumes of the carrier. Oleine acid formed on the alumina surface monolayer of coupled liquid phase.
